Using UART TX1, and RX1.

Development Boards ESP32
1

Hi,

I read that there are 3 UARTS on the ESP 32. You have told other forum questioners that TX0 and RX0 are used for the USB connection, but I have not found anything about TX1 and RX1. Is https://docs.espressif.com/projects/ard … aries.html

just dealing with the 0 port? Is the 2 port even brought out to a board pin in the Thing Plus?

Thanks, just trying to get all the information in front of me.
